Title: Manufacturing device for metallic tube
Inventor: MORI HIROAKI
IPC: F28F1/40
Filed: 1998-07-17
Granted: 2001-01-11
Abstract: Disclosed is a manufacturing device for a metallic tube used for heat-conductive tubes of a cooler or an air conditioner, or evaporating tubes, condensation tubes of heat exchangers. This invention relates to the manufacturing device for a metallic tube, which is formed with patterns, such as a slot and irregularity, on its internal surface, in order to improve the heat-transfer rate. This metallic tube making device is composed of a storing and feeding device which continuously feeds stored band-like thin metallic plates; an embossing device which forms a prescribed pattern to the thin metallic plate under feeding; a tube manufacturing device which forms the thin metallic plate into a tubular shape and joins both side end edges of the thin metallic plate; and a winder which winds a completed metallic tube. An adjusting device, which applies a prescribed tension to the thin metallic plate under feeding, is respectively provided among the storing and feeding device, the embossing device and the tube-manufacturing device for feeding the plate under a fixed speed to respective device. Because the metallic plate is constantly spread in an expanded, flat state between the storing and feeding device and the embossing device, and is fed under a fixed speed, the metallic plate can be formed in a precise manner and be prevented from moving in a zigzag direction in the shape of S character, bending, or undulating. Because a prescribed tension is normally applied between the embossing device and the tube-manufacturing device, and because the plate is fed under a fixed speed, when embossing is carried out, this invention can prevent the opposing edges of metal plate from deformation. As such, this invention can produce tubes of predetermined shape.

Title: Method and apparatus for driving piezoelectric transformer
Inventor: IGUCHI KOUICHI
IPC: G02F1/133
Filed: 1998-10-09
Granted: 2000-05-11
Abstract: A combination of two control methods are used, one of which is a method to control the boosting ratio of the piezoelectric transformer and another is a method to control the driving waveform of the piezoelectric transformer. The threshold values for switching the control methods are set with a hysteresis characteristic in order to avoid instability in the driving frequency at the time of switching and also to avoid driving at a natural frequency. When the source voltage is fixed, the driving frequency is increased by changing the resistance of the detection resistor 16 until the driving frequency reaches the natural frequency causing problems. When the driving frequency reaches the natural frequency causing problems. When the driving frequency reaches the natural frequency, the power supply to the driving circuit is reduced to reduce the amplitude of the driving wave for reducing the driving frequency without changing the output voltage. At this state when the amplitude is small, the minimum output  voltage is obtained by increasing the driving frequency to the natural frequency. This method and apparatus provide a wider range of output voltagea and reliable output characteristics of the piezoelectric transformer.

Title: Low power consumption mathematic apparatus and method
Inventor: CHEN OSCAL T-C
IPC: G06F7/57
Filed: 1999-05-06
Granted: 2002-12-21
Abstract: A kind of low power consumption mathematic apparatus is composed of the input master latch, the dynamic range detection unit, the control switch slave latch, the operation unit, and the bit number returning unit. In the mathematic apparatus, the input master latch is used to latch plural (for example two) input data. The dynamic range detection unit detects the effective dynamic range of these input data. The control switch slave latch is used for latching the bit number of the effective dynamic range of these input data. The operation unit performs the determined operation onto the bit number of the effective dynamic range so as to obtain an operation result. Because the operation unit only performs the operation onto the bit number in the effective dynamic range, the corresponding circuit of the remained bit number will not have switching power consumption and the operation of carrying a digit such that the entire power consumption is decreased. In addition, the bit number returning unit is used for complementing the operation result to the original output length such that an accurate operation result is obtained.

Title: Liquid crystal projector device avoiding thermal turbulence
Inventor: LIU HE
IPC: G02F1/13
Filed: 1999-05-20
Granted: 2001-09-21
Abstract: The present invention relates to a projector device having the liquid crystal module to prevent thermal turbulence. The liquid crystal module structure of the present invention comprises at least a liquid crystal display and three polarization plates disposed along the progressing direction of light, wherein the second polarization plate and the third polarization plate are located on both sides of the liquid crystal display, and there is a spacing between the first polarization plate and the second polarization plate, and their absorption axes are parallel. In addition to the effect of preventing the thermal turbulence of air flow effectively because there is a second polarization plate between the heat dissipating air flow passing through the gap and the liquid crystal display panel, the heat generated by absorbing the photon energy by the second polarization plate can be reduced effectively since the first polarization plate is a highly absorptive polarization plate which can absorb most of the photon energy in advance to thereby extend the lifetime of the second polarization plate and liquid crystal panel. Also, since the absorbing axis of the second polarization plate is parallel to that of the first polarization plate, the contrast of the liquid crystal projector can be increased, especially when the first polarization plate absorbs excessive photon energy and its performance decays.
